System and method for dynamically updating memory address mappings

A method for dynamically moving data from one memory location to another memory location, comprising the steps of:

• mapping bus addresses to memory unit addresses based on a plurality of mappings, said memory unit addresses identifying a plurality of memory locations including a destination memory location and a source memory location;
• storing a pointer at said destination memory location, said pointer identifying said source memory location;
• updating, while said pointer is stored in said destination memory location, at least one of said mappings that correlates one of said bus addresses with one of said memory unit addresses identifying said source location such that said at least one mapping correlates said one bus address with one of said memory unit addresses identifying said destination location;
• storing, subsequent to said updating step, a data value from said source memory location into said destination memory location;
• accessing said pointer from said destination location;
• and
• accessing, based on said pointer, said data value from said source location in response to said accessing said pointer step.

A method for dynamically reallocating memory, comprising the steps of:

• providing a plurality of mappers, each of said mappers having a plurality of mappings including a mapping that maps a particular bus address to a memory unit address identifying a source memory location;
• receiving bus addresses;
• mapping said bus addresses to memory unit addresses based on said mappings;
• accessing data based on said memory unit addresses mapped from said bus addresses;
• dynamically updating each of said mappers such that said particular bus address is mapped, by each of said mappers, to a memory unit address identifying a destination memory location;
• moving a data value from said source memory location to said destination memory location;
• executing an instruction during said updating step;
• accessing, during said updating step, one of said source and destination locations in response to said executing step;
• determining, based on data accessed in said accessing step, whether said one location has been updated via said moving step;
• and
• accessing said data value from one of said source and destination locations in response to said determining step.

A method for dynamically reallocating memory, comprising the steps of:

• mapping bus addresses to memory unit addresses based on a plurality of mappings, said memory unit addresses identifying a plurality of memory locations including a destination memory location and a source memory location, as least one of said mappings correlating one of said bus addresses with one of said memory unit addresses identifying said source location;
• determining that a data value is to be moved from said source memory location to said destination memory location;
• updating, in response to said determining step, said at least one mapping such that said at least one mapping correlates said one bus address with one of said memory unit addresses identifying said destination location;
• moving, in response to said determining step, said data value from said source memory location into said destination memory location;
• storing, prior to said moving step and in response to said determining step, an indicator at said destination memory location, said indicator indicating that said data value has yet to be moved into said destination location;
• and
• accessing said data value based on said at least one mapping and said indicator.
